Lower credit card interest rate scam

phone number 901-248-7430 alled me up and directed me to press number 1 to reach the company for credit card rate reduction. Upon doing so they requested if I had over $5,000.00 in debt and they wanted my credit card number to verify the debt. I requested their first and last name. The female speaking stated her name was Margarita but would not provide her last name. I attempt to find an address for the compant she refused to tell me then directed me to her supervisor "Ronald James". He again advised me he would lower my debt and requested my credit card number. I again requested as to the address of his company he stated Tallahasse Florida, but wouldn't not provide me with a street address. When I advised him I would look him up on the federal system because I felt he was trying to perpetrate a scam he stated "don't call this a scam and I'm going to hang up". I looked up the company "Account Services" on the internet and it advised of scam warnings. I said the internet site indicates you company is involed in scams. He stated "this is not a scam", I replied it sure appears that way; he stated "shutup" and hung up the phone.
